Field Details

lefts

public final Nodes.Node[] lefts

 Represents the targets expressions before a splat node.

     a, b, * = 1, 2, 3, 4, 5
     ^^^^

 The splat node can be absent, in that case all target expressions are in the left field.

     a, b, c = 1, 2, 3, 4, 5
     ^^^^^^^
 

rest

public final Nodes.Node rest

 Represents a splat node in the target expression.

     a, b, *c = 1, 2, 3, 4
           ^^

 The variable can be empty, this results in a `SplatNode` with a `nil` expression field.

     a, b, * = 1, 2, 3, 4
           ^

 If the `*` is omitted, this field will contain an `ImplicitRestNode`

     a, b, = 1, 2, 3, 4
         ^
 

rights

public final Nodes.Node[] rights

 Represents the targets expressions after a splat node.

     a, *, b, c = 1, 2, 3, 4, 5
           ^^^^
 

value

public final Nodes.Node value

 The value to write to the targets. It can be any [non-void expression](https://github.com/ruby/prism/blob/main/docs/parsing_rules.md#non-void-expression).

     a, b, c = 1, 2, 3
               ^^^^^^^
